Southern Californians endured a second straight day of near nonstop rain Friday but emerged from the event relatively unscathed.

Meteorologists say the storm that cut a wide path from Oxnard to Temecula is ready for its second act Saturday and that could include thunder, water spouts, tornadoes and definitely more rain.

“Really, what we are transitioning into is more showery type precipitation,” explained National Weather Service Meteorologist Kathy Hoxsie. “In the morning we had the widespread carpet bombing rain. Now, we’ll move into a more showery format.”

Showers will produce heavy bursts of rain, sometimes as much as three-quarters to 1 inch per hour. The chance of precipitation for Saturday is 100 percent, according to the NWS forecast. As the storm moves east, the Inland Empire, the San Bernardino Mountain resorts and the Coachella Valley will get the brunt of the remaining storm.

A cold front will drop snow levels to 5,500 feet. Rain turned to heavy snow in Big Bear around 4:30 p.m. Friday. The ski resorts in the San Bernardino Mountains are expecting 12-18 inches of snow by Saturday afternoon.

On Sunday, the chance of rain drops to 30 percent as many parts of Southern California will see partly cloudy skies, Hoxsie said.

In the foothills of eastern Los Angeles County, residents in homes near the devastation caused last month by the 1,952-acre Colby Fire nervously watched as sheets of steady rain doused denuded hillsides and sent rivers of mud into the streets.

But not one home was damaged and no one was injured in Glendora. A Glendora woman had to be rescued from her car on Hicrest Road as she attempted to drive through thick mud, authorities reported.

In Rosemead, a 24-year-old Arcadia man was driving in the 8800 block of Grand Avenue, stopped and attempted to direct traffic away from downed power lines. He told deputies he felt “a shock wave” and complained of tingling in his right arm. He was taken to the hospital.

The positive results are perhaps a testament to the indefatigable efforts of city workers and volunteers who packed 50,000 sandbags and lined hillside streets with two miles of K-rails days before the rains hit.

In an afternoon meeting that was part press conference, part pep talk, Glendora Police Chief Tim Staab spoke like a coach whose team had the lead at halftime. He warned of rain fatigue, especially to those 1,000 homeowners in the evacuation zone. “We still have a ways to go,” said the chief.

The foothill regions most vulnerable to dangerous mudslides received 4 inches in 24 hours and Staab said the city expected a total of 5 to 6 inches of rain by Saturday at 9 p.m.

In the San Fernando Valley, despite patches of flooding and various road closures due to the rains, there were no major car accidents reported Friday, according to the California Highway Patrol.

“Fortunately there hasn’t been anything major and no serious injuries,” said Officer Leland Tang of the CHP’s West Valley office.

During Friday’s morning commute, there were 158 accidents on freeways and streets between 5 a.m. and 9 a.m. During the same time period last week the CHP reported 46 traffic accidents.

In Burbank, the roof of a commercial building collapsed at 9:06 a.m. during heavy rains but no one was hurt, Burbank fire Capt. Peter Hendrickson reported.

On a non-commute day, the focus shifts to keeping residents out of the Los Angeles River and making sure the dams and reservoirs don’t spill their banks.

On Friday, three men and two dogs were rescued from the swift-moving water of the L.A. River in three separate incidents.

The CHP is keeping a close eye on water levels in the Sepulveda Basin, which could prompt the closure of the interchange between the 101 and 405 freeways if the water crests over the basin.

“It hasn’t happened in decades, but we’re keeping a close eye on it just in case,” Tang said.

The Los Angeles County Department of Public Works has 21 crew members patrolling storm drains, spreading grounds and pump stations. The Englewood Debris Basin in Glendora has seen 1 inch of mud flow and the Englewild Channel at Sierra Madre Boulevard is half full of mud, the county DPW reported.

Some of the biggest rainfall totals were recorded at rain gauges in mountains dams. Totals since Wednesday are: Morris Dam above Azusa, 3.24 inches; Newhall, 3.12 inches; L.A. River at Wardlow, 1.13 inches.

The county reports capturing 2,681 acre-feet of water during the storm, enough to supply 21,400 people for one year.
